It was pretty good. I would recommend it to anyone looking for something to watch simply for diversion. Do not watch this movie if historical or scientific inaccuracies would drive you crazy. It was about to drive me crazy with how much they ignored the Butterfly effect. They went back in time to save Chris's (played by Paul Walker) father. They went back to April 1357. They went there right before a major battle that supposedly took place. They changed a bunch of things in the past, but when they flash back to the present to show those that were left here to run the machine, nothing is changed. The people in the past also spoke the same dialect of French and English that we do now. That totally would not be the case. Also, the war that took place actually happened, but the major battle they supposedly take part in did not. So if none of that would bother you, and you want to just watch a movie for entertainment, this is a good movie.
